Brewing & Fermentation Temperature Dashboard
Log temperature readings for a fermenting beer or wine batch (ale range) and watch latest, average, min/max, in-range % and excursions against a °C acceptable band.
Acceptable band: 18–22 °C. Readings are timestamped and stored in your browser only.
Acceptable band 18–22 °C. Times use this device's clock (2026-06-08).
Field notes from maintenance practice
Measure the beer, not the room: vigorous fermentation can run 3–5 °C above ambient from its own heat, so a thermowell or a stick-on fermenter strip beats an air thermometer. The first 72 hours are when temperature control matters most — that's when the yeast throws the compounds you'll taste. Yeast makes the flavour, and temperature controls the yeast: too warm and ales throw harsh fusel alcohols and excess esters, too cool and fermentation stalls — and active fermentation is exothermic, so the beer runs warmer than the room by several degrees at peak.
Consistency makes the numbers meaningful: measure at the same point, with the same instrument, at sensible intervals (continuous where the risk is high, spot-checks where it is low). The in-range percentage is the metric to watch — a band that quietly drifts from 100% toward 95% is telling you something is changing before any single reading alarms.

About Brewing & Fermentation Temperature Dashboard
This dashboard turns scattered temperature checks for a fermenting beer or wine batch (ale range) into a monitored series: log a reading whenever you measure and it tracks the latest value, the average, the min/max range, the percentage of readings inside the acceptable band and the number of excursions — the everyday telemetry picture, computed in your browser with no logger subscription. The default acceptable band is 18–22 °C for typical ale yeast (lagers ferment far cooler, 8–13 °C).
How to use Brewing & Fermentation Temperature Dashboard
- 1Log a reading whenever you measure — each is timestamped and stored in your browser.
- 2The dashboard shows latest, average, min/max, in-range % and an excursion count against the acceptable band.
- 3Watch the sparkline and the in-range percentage — a falling in-range % is your early warning before a hard excursion.

Frequently asked questions
What is the acceptable temperature range for a fermenting beer or wine batch (ale range)?+
The default band is 18–22 °C for typical ale yeast (lagers ferment far cooler, 8–13 °C). Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.
Should I control to ambient room temperature or wort temperature?+
Wort temperature, always — that's what the yeast experiences. During the most active phase, fermentation heat can lift the beer well above the room, so a room held at 20 °C might have beer fermenting at 24 °C and producing off-flavours. Use a thermowell or a stick-on LCD strip on the fermenter, and ideally a controller that drives a fridge/heater off the beer probe (a 'fermentation chamber'). Hold the band tightest during the first few days of high activity.
How often should I log temperature readings?+
Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.
Is my logged data private?+
Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
